Default Re: Motor control board repair

Well, I found the problem causing no -15V. It's the connector. It's not making good contact, but I'm sure I accidentally bent that pin when I was originally trying to measure transformer output voltages. So I'll have to either fix that or replace the connector. I've seen this type before so I assume I can find one.

So now I guess I power it up on 120V with attention to that connector and see what I get.
